Automatic fare adjustment system and memory device for transportation system

Abstract

An automatic fare adjustment system is provided for train systems for which more than on service provider operates trains. It is possible to prevent illegal use of a memory device. The memory device 10 stores ID information and information about settling methods, fare imposition, free transportation sections that are covered by commuter passes, coupon tickets, etc, and travel history. A transmitter 20 at an automatic ticket gate for boarding 1 sends information about the boarding station to the memory device 10. Onboard a train, information about an intermediate station is sent from an onboard transmitter 30 to the memory device 10. A fare imposing unit 40 at an automatic ticket gate for detraining 4 carries out fare imposition processing based on the above-described information and information about boarding and intermediate stations. The transmitter 20 and the fare imposing unit 40 send information stored in the memory device 10 to a host computer 50, where the information is compared with the information about settling methods and travel history stored in the host computer 50 to make sure that the particular memory device is valid.

1 . An automatic fare adjustment system comprising: 
 a memory device having a signal transmission/reception function which stores ID information, and information about a settling method and a free transportation section;    a first transmitter having a signal transmission/reception function, which is provided in the vicinity of a boarding-side automatic ticket gate to send information about boarding station to said memory device;    a second transmitter for sending information about an intermediate station to said memory device; and    a fare imposing unit having a signal transmission/reception function which is provided in the vicinity of a detraining automatic ticket gate to carry out fare imposition processing by receiving said ID information and information about the settling method, free transportation sections, boarding station and intermediate stations from said memory device.    
     
     
         2 . The automatic fare adjustment system according to  claim 1 , wherein said memory device further stores travel history information; 
 said system has a host computer connected to said first transmitter and said fare imposing unit, which host computer stores travel history information for each ID of memory device; and    said host computer judge as to whether or not said memory device is valid by comparing the travel history information stored in said memory device with the travel history information of the ID of said memory device stored in said host computer.    
     
     
         3 . The automatic fare adjustment system according to  claim 1  or  2 , wherein said host computer stores information about settling method for the ID of each memory device, and makes judgment as to whether or not said memory device is valid by comparing the information about settling method stored in said memory device with the information about settling method of the ID of said memory device stored in said host computer.  
     
     
         4 . A memory device for a transportation system having a signal transmission/reception function, which stores ID information, information about a settling method, a free transportation section, and travel history, and receives information about boarding and intermediate stations from an outside unit and stores said information.  
     
     
         5 . The memory device for a transportation system according to  claim 4 , wherein said memory device further has an input section and an output section, and is provided with a function of comparing information about a station inputted through said input section with information about the station received from said outside unit and of outputting the comparison result on said output section.
